Description:

Abstract:

This data represents the lakes reported in the 2004 Integrated Report. There are approximately 3,278 lakes, reservoirs and ponds over 2 acres size in New Jersey, but of these, only about 60 are natural. The remainder are constructed impoundments. There are 380 public lakes (24,000 acres) and 64 reservoirs.

Purpose:

This data spatially represents lakes over 2 acres in New Jersey and was used as the base coverage for lakes in the 2004 Integrated Report.

2004 Integrated Report files retain the same basic content as the 2002 Integrated Report, with small changes in format. Some files were combined to consolidate information. For questions on metadata content, please contact Leigh Lager, NJDEP/BFBM 609-292-0427 or leigh.lager@dep.state.nj.us

Lake polygons and names are based on NJDEP Lakes with Name Attributes for the State of New Jersey. Assessment results were imported from NJDEP Water Assessment Team's data files of aquatic life assessment results, and included verification check with approximately 90% of the entries.

Logical_Consistency_Report:

Removed any known artificial waterbodies such as treatment plants, holding ponds, detention basins, or wide rivers with no known dams that were mistakenly identified as lakes. This process was completed by reviewing the 1995/97 orthoquads.

Completeness_Report: Did not include lakes and ponds smaller than 2 acres.

Source_Contribution: Lake polygons used as base coverage

Process_Step:

Process_Description:

Used NJDEP Lakes with Name Attributes for the State of New Jersey as the base coverage. The following edits were completed to improve and simplify the lakes: a) deleted all lakes smaller than 2 acres; b) using the 1995 orthoquads, added any missing lakes or deleted lakes that were obviously detention basins, cranberry bogs, man-made structure holding water (i.e. settling tank at STP), or wide river without a dam. Checked approximately 60% of the state; c) Lakes that were known to be hydraulically connected were merged together to create one lake (polygon).
Additional lake names were manually matched using recreational lakes that were GPS'd, dam names, and atlases. Each lake was assigned a unique name by adding the watershed management area (WMA) number to the lake name. Lakes with unknown names were assigned the name "Lake" followed by a index number and the WMA number.
Intersected the coverage with watershed management area and HUC 11 coverages to identify lake location by watershed management area, HUC 11, HUC 8, and region.
